🔍 Technical Background

The NTG4.5 and NTG4.7 COMAND units are advanced infotainment systems that integrate radio, navigation, Bluetooth, vehicle settings, and more. Over time, common failures include internal flash corruption, faulty power modules, and processor-level defects that cause boot loops, display freeze, or total failure.

In many cases, dealer replacement costs can exceed $2,500–$4,000, and used units often require VIN coding or SCN programming. With our repair, you keep your original unit and avoid coding headaches.
